Description

If you are someone who is preparing for Java Microservices interviews and wants to feel confident and well-prepared. If you want to gain confidence and expertise in Java Microservices, this course is designed to help you achieve that and more! Whether you are aiming to land your dream job or simply want to enhance your expertise, this course is going to be your ultimate resource.

What You'll Learn:

Concepts + Practicality = Mastery:

We don’t just cover theoretical knowledge. Every concept is backed by hands-on coding exercises and practical scenarios that simulate real-world challenges. You’ll learn not just how microservices work, but how to apply this knowledge in real projects through these practice tests.

1. Diverse Question Types: Encounter a wide range of question types, including:

   • Concept-Based Questions: Test your understanding of core principles, ensuring you have a solid foundation in Java Microservices.

   • Code-Based Questions: Solve real coding problems that enhances what you will face in technical interviews, proving your practical skills.

   • Scenario-Based Questions: Apply your knowledge to real-world situations, preparing you for the complexities of actual projects and interviews. It includes detailed scenarios, such as handling service failure in a distributed system or scaling microservices, to demonstrate how to apply concepts in real-life situations.

   • Single-Select Questions: Focus on specific key concepts with questions that require you to identify the one correct answer.

   • Multi-Select Questions: Engage with more complex scenarios that require a deeper understanding and the ability to identify multiple correct answers.

2. Diverse Range of Topics: Gain mastery over essential microservices concepts and tools, including:

   • Microservices Architecture: Understand the foundational principles that guide scalable and maintainable systems.

   • Service Registry & Discovery: Learn how to use tools like Eureka, Zookeeper, and Consul for service management.

   • Feign Client: Explore how Feign simplifies HTTP communication between microservices.

   • Config Server: Manage configurations and control a central place for managing external properties for applications across all environments.

   • API Gateway: Learn how to handle all incoming API requests and routes them to the appropriate microservice, and functionalities like request routing, load balancing, security, rate limiting, and monitoring.

   • Fault Tolerance: Implement resilience strategies with Resilience4j and Hystrix.

   • Message Brokers: Explore asynchronous communication using RabbitMQ, Kafka, and other message brokers.

   • ELK Stack: Monitor and analyze logs efficiently with Elasticsearch, Logstash, and Kibana.

   • Sleuth & Zipkin: Trace microservices interactions for effective debugging.

   • Scalability & Performance Monitoring: Ensure your microservices can scale and perform under load.

   • Microservices and DevOps Integration: Understand the seamless integration of microservices with CI/CD pipelines.

   • API Versioning: Learn best practices for evolving APIs in a microservices environment.

   • Logging, Database Management, and Containerization: Manage logs, databases, and deploy microservices with Docker and Kubernetes.

• Comprehensive Practice Tests: Explore a wide range of challenging practice questions designed to test your understanding of key Java Microservices concepts from beginners to experts.

• In-Depth Explanations: Each question is followed by a detailed explanation, so you not only know the right answer but also understand why it’s correct. For example, in a question about microservices communication, the explanation would cover not just the correct method (like REST vs. messaging) but also why other options might be less effective or unsuitable in certain contexts.

• Sample Question: Here is a sample question of the Practice Tests:

  
  

  Below are three statements about the Strangler Pattern in microservices:

  
  

  1. The Strangler Pattern is used to add new features to a microservice.

  2. It helps in gradually refactoring a monolithic system into microservices.

  3. The Strangler Pattern requires rewriting the entire application at once.

  
  

  Which of the following is the correct option?

  
  

  (A) Statements 1 & 3 are correct

  (B) Statements 2 & 3 are correct

  (C) Statement 2 is correct

  (D) All statements are correct

Correct Answer: (C)

Explanation:

1. The Strangler Pattern is used for migrating from a monolithic architecture to microservices, not just for adding new features (Statement 1 is incorrect).

2. It allows for gradual refactoring, replacing parts of the monolith with microservices over time (Statement 2 is correct).

3. This approach does not require rewriting the entire application at once (Statement 3 is incorrect).

This course doesn’t just prepare you for interviews, but it prepares you for the real-world challenges you will face as a software developer.

If you find any question erroneous, kindly provide your feedback. The same will be corrected on priority.
